ALEXANDER IBOGDANFFY, OF NEW YORK, N. Y., ASSIGNOR TO INTERNATIONAL CORKCOMPANY, OF BROOKLYN, NEW YORK, A CORPORATION OF NEW YORK.

CORK-SHELL-GUTTING MACHINE.

To all whom it may concern:

Be it known that I, ALEXANDER BOG- DXNrrY, a subject of the King ofHungary, and resident of the city of New York, in the county of Kingsand State of New York, have invented certain new and useful Improvementsin Cork-Shell-Gutting Machines, of which the following is aspecification.

The present invention relates to an improved apparatus for cutting corkshells, or, as they are sometimes termed hollow corks.

One of the objects of the invention is to construct an improvedapparatus for cutting cork shells, by means of which the work isaccomplished automatically by one setting of the cork strips and by oneoperation of the machine.

Another object of the invention is to produce a machine that may beoperated without employing skilled labor, and which is simple inconstruction and efficient in operation.

With these and other objects in view, which will more. fully appear asthe nature of the invention is better understood, the same consists inthe combination, arrange ment and construction of parts hereinafterfully described, pointed out in the appended claims and illustrated inthe accompanying drawings, it being understood that many changes may bemade in the size and proportion of the several parts and minor detailsof construction without departing from the spirit or sacrificing any ofthe advantages of the invention.

One of the many possible embodiments of the invention is illustrated inthe accompanying drawings, in which:

Figure 1 is a front elevation of a cork shell cutting machineconstructed in accordance with the present invention; Fig. 2 is an endelevation thereof; Fig. 3 is a vertical longitudinal section through thecombined cutters and stripper; Fig. 4 is a section taken on line 4-4 ofFig. 3; Fig. 5 is a section taken on line 55 of Fig. 3; and Fig. 6 is avertical longitudinal section of a detail of construction,

In the drawings, the numeral 10 designates the bed frame of the machine,which rests on legs or standards 11, 11, carrying bearings 12, 12, inwhich the driving shaft 13- of the machine is journaled. Rotation may beimparted to this shaft in any suit- Specification of Letters Patent.

able manner, for instance by keying to the same a pulley 14, which isdriven by means of a belt or otherwise. The bed frame 10 supportsbearings 15, 16 and 17 of any suitable construction, in which arerotatably and reciprocatably arranged the cutting and stripping means ofthe machine. These cutting and stripping means are shown in detail inFigs. 3 to 5, inclusive, and comprise a tubular arbor 18, journaled inthe bear ings 16 and 17, and provided in its front portion with innerscrew threads 19, meshing with the outer threads 20 of a tubular corkcutter 21. l/Vithin the arbor 18 is slidably arranged a tubular member22, the outer diameter of which is considerably smaller than the innerdiameter of the arbor 18. To this tubular member is fastened a collar23, which, together with the collar 24, that is attached to the arbor18, holds the tubular member in concentrical relation relative to saidarbor. The tubular member 22 is at its front portion provided with innerscrew threads 25, which mesh with the outer screw threads 26 of a secondtubular cork cutter 27. The cutter 21 serves to cut the exterior of thecork shells from the cork strips, while the cutter 27 cuts out the corefrom the shell. The arbor 18 is provided with a longitudinal slot 28,the walls of which are engaged by a pin 29, which is secured to thecollar 23, whereby the tubular member 22 will rotate with said arbor,while its reciprocating movement is independent of that of said arbor.

For removing the finished product from the cutter, a tubular stripper 30is slidably arranged between the cutters 21 and 27. To the inner end 31of this cutter is attached a ring 32, which is adapted to bear against ashiftable sleeve 33, the latter being located between the arbor and thetubular member 22 and its cutter 27. Against this sleeve and the collar23 bears a spring 34, which is coiled upon the tubular member 22. Aspring 35, also coiled upon the tubular member 22, bears against thecollar 24 and a ring 36, which latter is attached to the tubular member22. This ring is provided with a peripheral groove 37, which is normallyengaged by dogs 38, 38, arranged in slots 39, 39 in the arbor 18, andpivoted to the latter at 40, 40. Springs 41, 41 hold the noses 42, 42 ofsaid dogs in engagement with the groove 37. When the noses 42 of thedogs 38 engage the groove 37 in the ring 36, the arbor 18 and thetubular member 22 will reciprocate together. It will appear hereinafterthat, at certain points in the longitudinal movement of the two cutters,the same must reciprocate independently of each other. For this purposeit becomes necessary to disengage the dogs 38 from the groove 37 in thering 36. To this end, a tubular extension 43 is arranged upon thebearing 17, the inner diameter of said extension being smaller than thedistance between the outermost points of the free ends of the dogs 38.The dogs and grooved rings form a clutch, as it were.

From the foregoing it will be observed that the two cutters of themachine are made to rotate together in their bearings, and that theymove back and forth together when the dogs 38 are engaged with the ring36, and independently of each other when said parts are disengaged fromeach other. The stripper 30 reciprocates with the cutters in a mannerwhich will be hereinafter described. The cutters 21 and 27, and so alsothe stripper 30, can be easily replaced by others as shells of differentsizes are to be made.

Rotary motion is imparted to the cutting and stripping mechanism, forinstance by means of a belt 44, running over a pulley 45, which is keyedor otherwise attached to the arbor 18, and over a pulley 46, mountedupon the driving shaft 13. It will be observed that, since the pulley 45travels with the arbor 18, the height of the cylindrical surface of thepulley 46 must be at least as much as the width of the belt 44 plus theamount of the reciprocatory movement of the arbor 18 in one direction.

A back and forth movement is imparted to the cutting and strippingmechanism from a treadle 47, which is pivoted at 48 to a standard 49 andattached to or made integral with a bar 50, the upper end of which isfork-shaped, as clearly shown at 51. The prongs of the fork are providedwith slots 52, in engagement with pins 53, 53, carried by a ring 54,which is loosely mounted upon the arbor 18 and held against longitudinalmovement thereon by means of stop-rings 55, 55. Between the ring 54 andthe rings 55 are arranged a plurality of balls 56, 56 for well knownpurposes. A spring 57, bearing against the treadle 47, tends to hold thesame in its normal elevated position.

The cork strips are held in operative relation to the cutters andstripper upon a support 58, which is attached to a bracket 59, thelatter being fastened to one of the standards 11 of the machine. Thesupport 58 includes a vertical plate 60, carrying substantiallyhorizontal lugs 61, provided with slots 62, which are engaged by screwthreaded spindles 63 of a second vertical 65, whereby the plate 64 maybe set relative to the plate 60 to a distance which correspondssubstantially to the thickness of the V cork strip 66 to be worked upon.This cork strip rests upon a. base plate 67, which is attached to a lug68, having a slot 69, engaged by a screw bolt 70, which is attached tothe support 58, and meshes with a nut 71. By means of this arrangement,the base plate 67v can be raised or lowered as the corkstrips vary inheights. The plates 60 and 64 are provided with apertures 60 and 64,respectively, in the longitudinal axis of the arbor 18.

The cork strips are fed to the cutters by hand, and the finished productis adapted to fall into a chute 72, to be conducted into a receptacle 73standing upon the floor. The cores of the shells pass through thetubular member 22 and drop into a chute 74, which is arranged at theouter end of the tubular member 22 and conducts the said cores into a.receptacle (not shown in the drawings).

The operation of the device is as follows: Normally the parts are in theposition shown in Figs. 1 and 3 of the drawings, that is to say the stop22, which is attached to the tubular member 22, bears against thebearing 15, and the two cutters are adapted to reciprocate together byreason of the dogs 38 being in engagement with the ring 36. In thesepositions, the springs 34 and 35 are compressed. The operatorplacesthecork strip upon the support and forces the treadle 47 downward in thedirection of the arrow shown in Fig. 1 of the drawings. The rotarycutters and stripper are by this movement of the treadle caused to movetoward the cork strip 66. The cutting edge of the cutter 27, being aheadof that of the cutter 21, will first enter the cork strip and performthe cutting operation as the rotating cutters and stripper are beingadvanced. As soon as the cutter 27 has cut the core of the cork shell,the free ends of the dogs 38 will be forced toward the longitudinal axisof the arbor 18 by the extension 43 of the bear ing 17, and bedisengaged thereby from the ring 36. As soon as this takes place, thetension of the springs 35 and 34 will be released, whereby the spring 35will force the tubular member 22 toward the bearing 15 so that its stop22 will abut against said the spring 57 raises the same, and shifts thearbor 18 toward the bearing 15, when the springs 11 will lower the noses42 of the dogs 38 into the groove 37 of the ring 36. In the meantime,however, the springs 34 and 35 are again compressed. As the spring 34 isbeing compressed, it stops the movement of the stripper 80 so that, asthe arbor 18 is being moved toward the bearing 15, the cork shell willbe pushed by the said stripper into the chute 72. The parts are then inpositions to start again the cycle of operation now described. Theoperator advances then the cork strip upon the workholder a distancewhich is somewhat larger than the shell, places again his foot upon thetreadle 4:7 and the play is repeated.
